Forgive my description of these items as I am not at my editing computer to confirm proper verbiage.
I use two monitors and, in PS, have them set up so the workspace is on the main monitor so only the image takes up that space, while all the editing dialogue boxes etc are on the second monitor.
Having said that, when I open a raw image (via PS) in Camera Raw, CR opens on the main monitor, with the image area and all the editing dialogues etc in the same panel(?).
Is there an easy way to separate the CR workspace/image area from the editing dialogues so I can do the same as PS above? I took an amateurs run at it with no success.
